I have the avro files generated by Event Hub Capture & stored in ADLS Gen1. Now I would like to migrate all these files ( size ~6 TB) to ADLS Gen2. During migration process, I don't want event hub capture to generate new avro files & place in old Gen1 path hence wondering if there is a way to temporarily stop "Capture" & re-enable it back post data migration & reconciliation activities (i.e. changing path to ADLS Gen2) ?

If I "disable" Capture using UI , is there any chance of data loss on re-enabling the setting ?

P.S. I am using event hub dedicated cluster & it has retention period of 90 days. Also,can't ask publisher to stop sending events during this migration.

CodePudding user response：

Sure, you can disable the capture temporarily. However, make sure your retention period is long enough - 90 days for dedicated, that no data is purged w/o being captured.
